When it comes to Price meets performance you really can’t go past the Dynojet EFI Tuner module for your EFI Tuning Needs. These are Highly programmable. You can even do a LIVE DYNO TUNE using one of these which is a feature that a lot of other EFI units do not offer.

These are basically identical to the Dynojet Power Commander but are cheaper and do not have programming buttons on the unit. The programming buttons are for programming the unit WITHOUT a computer hence we recommend these as 99%+ of people would not program these with the buttons anyway. These can be programmed one of two ways:

1: You can download a MAP file and install it into the unit via a USB cable using your own PC or notebook. You can do this while it is installed on the bike or even off the bike using the 9 volt battery adaptor that comes in the box.

2: You can put the bike on a DYNO and dyno tune it LIVE doing power runs to get the best match to your particular bike. This is not really necessary for bikes without engine modifications and we can usually supply the unit with a map to suit your bike without going to this costly extreme BUT for those who have made engine modifications such as Cam, bore, pistons, heads or those who have a custom exhaust or air filter then this option is essential.

How it works:

The Dynojet EFI Tuner plugs inline with your bike�s stock fuel injection system. It uses OEM (original equipment manufacturer) style connectors making installation easy and quick. The Dynojet EFI Tuner allows a full range of fuel adjustment, as much as +/- 100% over stock. Adjustments can be made either with a Windows based computer or by using the face plate mounted button adjusters. No permanent changes are made to the bike�s system. Once the unit is removed the bike reverts to its stock settings.

Dynojet EFI Tuner & Power Commander Map Database:

Dynojet supports the Power Commander product line with the worlds largest map database. We work with all of the leading exhaust manufacturers from around the globe to bring you pre-tested settings for your motorcycle. No guesswork on your part. Every map that we offer was tested and developed on one of our multiple in house Dynojet Dynamometers using our patented Tuning Link software. New maps are developed weekly for all popular applications.

Other great features include:

Hassle free USB communication – The Dynojet EFI Tuner will instantly and automatically connect to the Power Commander Control Center software once it is installed. Simply “power up” the unit and connect the supplied USB cable to the computer and EFI Tuner.

Onboard notes storage – The Dynojet EFI Tuner stores the notes from the map in the onboard memory. This makes it easy to see exactly which map is loaded. The notes, just as the map itself, are automatically retrieved upon connecting to the unit.

Individual cylinder adjustment – All Dynojet EFI Tuner units have a “cylinder trim” adjustment feature that allows you to “offset” fuel to one or more cylinders. Additionally, for advanced users, the EFI Tuner allows individual cylinder mapping. Now each cylinder can be mapped individually throughout the entire rpm/throttle position range.

Enhanced “file compare” utility – The Dynojet EFI Tuner software allows you to compare two map files without the EFI Tuner connected. There is a numerical display as well as a brand new graphical display.

Easier to use “button adjustment” mode – The button adjustment has been made easier by introducing a “startup delay”. This lets the user have enough time to start the bike and then switch the EFI Tuner into “button adjust” mode. The ranges of the buttons are now displayed in the software. Simply connect the unit to the computer and press one of the buttons. Their ranges are shown on the screen.

“Expansion port” for upgrades and accessories – The “expansion port” allows easy connection of accessories such as our new ignition module, Quick shifter, Multifunction Hub, Pressure Sensor display and LCD display unit. Automatic map retrieval upon connection – As soon as you connect the EFI Tuner to the computer and launch the software, the map installed in the EFI Tuner will be displayed.

9V “Power Up” adapter – Every EFI Tuner comes with a “power up” adapter which allows users to program and interface with the EFI Tuner on their desktop without being connected to the bike. Accelerator Pump – You can adjust: A) The amount of fuel to add, B) The number of engine revolutions during which fuel is added, C) The sensitivity of throttle movement under which the accelerator pump is activated.

Additional Features for Harley Davidson

� The first new feature is “Rev X-tend”. This will give you the ability to have an increased rev limit over stock without having to modify the bike’s ECM. No longer will you need to take the bike to the dealer to have the ECM “re flashed” in order to have the higher rev limit your bike needs with modified cams, heads, etc.

� The second new feature is “Start Fuel”. This allows you to add additional fuel during startup. On heavily modified and/or large displacement engines (i.e. 124 Cubic Inch) extra fuel is sometimes required to ease starting. This is a software adjustable setting that makes it possible to increase the amount of fuel injected into the engine during cranking without making the idle overly rich once the engine starts.

How much additional power will it give my motorcycle?

There are many variables to each application. The Dynojet EFI Tuner allows for tuning to the perfect air/fuel ratio will ensure that the engine can produce the maximum possible horsepower for that given combination.

Consider that a typical street rider spends a great deal of time riding in part throttle conditions. Shown below are two graphs of a motorcycle before and after installation of the Dynojet EFI Tuner. The top graph line shows the horsepower curve accelerating and the lower graph shows the corresponding air/fuel ratio. You can see a large horsepower increase between the two. The red curve shows a typical stock motorcycle with minor performance modifications (slip-on exhaust).

The blue curve shows that same combination with the Dynojet EFI Tuner installed and you can see that the line is nearly straight. Consequently, the rider will feel a large improvement while riding the motorcycle. It is very possible that the peak wide open throttle horsepower is unchanged. The correct air/fuel ratio number (say 12.9:1 or 13.2:1) depends upon many factors like combustion chamber design, but what we want is that figure at every point in the curve (straight line).

Tuning with Dynojet EFI Tuner

Base Map – The Dynojet EFI Tuner is supplied with a given (base) map stored in the microprocessor. This (base map) is typically a map that has been developed to provide an improvement for most combinations matching the map description (i.e. stock bike or performance exhaust and air filter).

In general we have found that a typical stock bike has areas in the fuel curve that are far from optimal for drive-ability and performance. We could say that they are typically 70% optimized in stock condition and 60% – 65% with minor performance modifications. After installation of the Dynojet EFI Tuner with the base map, we would expect to see 85% – 95% optimization. EFI Tuner Alternate Maps – Each Dynojet EFI Tuner is supplied with a number of alternate maps on a CD-ROM and all the maps are available for download on our web site.

You may notice that we have a map specifically for “Brand A” slip-on exhaust and another for “Brand B” slip-on exhaust. Although the difference between the two maps is likely to be very small, these difference will increase the optimization for that given combination. If you have a “Brand C” exhaust and we do not have a specific map, you should find that “Brand A” or Brand B” maps will provide a good improvement on your bike. If you have a Windows 98SE/ME/2000/XP computer, you can upload alternate maps or make changes to the existing map using the Control Center software and USB cable supplied with your PC. (Detailed Software tutorials and quick reference software screen shots are available on the CD-ROM or web site).

If you do not have a computer, you can change the fuel curve with the faceplate buttons. This is a simple adjustment that can move the fuel curve richer or leaner in each area of the map. (Please refer to the paper installation guide or adjustment video on the CD-ROM).

Also there is a HUGE Range of optional accessories available. Some available for Power commander III and V and Dynojet EFI Tuner and some only for either. Email us if you are not sure which you need or are available.

A Dynojet EFI Tuner is the most important of the THREE parts of the stage 1 upgrade when it comes to power increases and this is where we excel in the industry. We have 12 years in EFI tuning experience from motorcycles to turbo and supercharged circuit and drag race cars. Please call us to discuss which EFI unit is the best for your particular bike. With certain models, we will PRE-PROGRAM the unit FREE OF CHARGE before we ship it to you to fit your bike and this will save you a COSTLY DYNO TUNE. The unit will arrive already programmed to suit your bike as if it had been dyno tuned by us but without all the cost and hassle… and you know it has been done right!

WARNING: The other important thing to know about Australian Model Harley-Davidson Motorcycles is that they come out with an ACTIVE EXHAUST MODULE which does NOT come out on American Models so it is important to know this before you purchase! VERY IMPORTANT!

These are the KEY ingredient when performing a Stage 1 upgrade which can result in up to 20% Horse Power increase and more importantly will stop your bike running LEAN and will also make it run COOLER. It will also remove (in most cases), or at least reduce that nasty POPPING sound on deceleration and replace it with what I think is a much nicer sound.

So be sure to call us and discuss your stage 1 upgrade on your bike. It is imperative that you pick components that will work well together and that are well catered for when it comes to downloadable MAPS for your EFI Module. We are experts in this and only to happy to help!
